JAVA PROGRAM CÓ 2 INNER CLASSES

JAVA PROGRAM HAVING 2 INNER CLASSES.

   class Inner1 { … } and  class Inner2 { … }

1-  Compiler của Ideone.com phải dùng outer class là class Main.

public class Main {  

        String outerStr = " String in the class outer : THÂN CHÀO QUÝ BAN !\n"  ;

class Inner1 {

         String inner1Str = " String in the class Inner1 : \n" ;     

        String display1(String parameter) { 

        return   outerStr+ inner1Str + parameter ;  }       

        }   

    public static void main(String[] args) {

        Main outer = new Main();  

                        outer.run() ;

        Main outer1 = new Main();  

                         outer1.go() ;  }   

       void run() {  

        Inner1 local = new Inner1();

        System.out.println(local.display1(" Hola Amigaso ! COMMO ESTA ?"));

        }

       void go() {  

        Inner2 in2 = new Inner2();

        System.out.println(in2.display2("Hello Friends ! HOW ARE YOU ?"));

        }

class Inner2 { 

        String inner2Str =  "  String in the class Inner2 :\n" ;     

        String display2(String parameter) { 

        return inner2Str +  parameter ;   }        

     }

}

Output.

SUCCESS

String in the class outer : THÂN CHÀO QUÝ BAN !

 String in the class Inner1 : 

 Hola Amigaso ! COMMO ESTA ?

  String in the class Inner2 :

2- Compiler của Rextester.com

class Rextester {  

        String outerStr = " String in the class outer : THÂN CH̀ÀO QUÝ BAN ! \n"  ;

class Inner1 {

         String inner1Str = " String in the class Inner1 :\n" ;     

        String display1(String parameter) { 

        return  outerStr + inner1Str + parameter ;  }       

        }   

    public static void main(String[] args) {

        Rextester outer = new Rextester();  

                        outer.run() ;

        Rextester outer1 = new Rextester();  

                         outer1.go() ;  }   

       void run() {  

        Inner1 local = new Inner1();

        System.out.println(local.display1(" Hola Amigaso ! COMMO ESTA ?"));

             }

       void go() {  

        Inner2 in2 = new Inner2();

        System.out.println(in2.display2("Hello Friends ! HOW ARE YOU ?"));

        }

class Inner2 { 

        String inner2Str =  "  String in the class Inner2 :\n" ;     

        String display2(String parameter) { 

        return inner2Str +  parameter ;   }              

     }

}

output.
